UNE'F :1 s'rs'rss PATENT OFFICE BEGULATING TOOL Frank U. Allen,Milwaukee, Wis. Application August 10, 1932, Serial No. 6283M 1 Claim.(01. 81-3) This invention relates to implements particua cushioningspring 6.

The occasions for its use are in the adjustment of a regulating screw,rod, or like element M with the screw-driver D while loosening andholding the jam-nut N with the wrench W. As shown the adjustment relatesto an engine part, or rocking lever E, while said lever is rapidlyoscillating. The spring 6 holds the screw-driver out of the wayautomatically which latter may be easily depressed to pick out ascrew-slot whose location above the nut N will vary. The wrench W isheld on the said nut after locating same, by downward pressure on themember D while the tool travels up and down with the rocking parts. Theconveniences residing in an implement of the concerned design permits ofmaking necessary adjustments under all conditions. The cap-likenut-socket S may be readibr slipped over the end M as a hood, even inthe dark; the screw-slotted end being freely enterable into the socket,thus maintaining a guiding relationship to aid in registering the socketportion around the oscillating nut. It-is only while a motor is warm andrunning that adjustments can be made with any degree of precision.

Having described the invention what is claimed and desired to protect byUnited States Letters Patent, is:-

In a regulating tool the combination; an in-' tegral lever arm andsquared plug formation; separated and axially aligned bearing meanshaving dowel-slots, at the plug and arm formations, for a normallyinseparable screw-driver element; said element provided with a shankdowel; said element rotatively free in the plug portion only whendepressed; said means allowing detachment of said element when thelatter is depressed and purposely rotated to dispose said dowel inregistry with the aforesaid slots; said squared plug devised toaccommodate commercial nutsockets.
